In 1993, The New Yorker published a cartoon by Peter Steiner of two dogs at a computer that became an instant classic, tacked up on bulletin boards everywhere. The caption: “On the internet, no one knows you’re a dog.”

A recent survey of a group of 98 tech-savvy Stanford students shows that the world Steiner depicted may be behind us. Asked about how they behave—or would behave—in a variety of situations online, students painted a picture that looked surprisingly like real life.
